Optosensing offers a compact and efficient measurement unit, the OSD-1, that can be remotely controlled by a PC or workstation.

By a proprietary software package, OSD-1 can handle readings with acquisition frequency up to 200Hz.

The spatial resolution, i.e. the fiber length over which strain or temperature are averaged, is as low as 20 cm; the spatial sampling is 5 cm; the sensitivity is better than 10µε and the measurement range is 10 km.
